Question

Find the surface area of a sphere with radius 5cm. Round your answer to the nearest tenth.

Answer 1

The surface area is 314.2

The formula of the sphere to find surface area is A = 4•3.14•r^2 , substitute 5 for r, then multiply 5^2, after you get that product then multiply it by 3.14/pi. Once you get that product, multiply that by 4 and you get the final product. Then round to the nearest tenth, which is how you get 314.2
